3.9.6 Min/Max Log Amps (Address 4600)
Use this address block to display the minimlJTI and maxi-
mlJTI current values measured by the relay. The available
measured values are listed in Table 3.26.
This log contains minimlJTI and maximlJTI values measured
by the relay while not in pickup. The collected information is
coJ'Tl)ared against previously stored values and the log is
updated.
AI
logged values are tine stamped and resetting
the log (see section 3.13.2, address block 8200) will reset all
log values.

3.9.7 Min/Max Log Volts (Address 4700)
Use this address block to display the minimlJTI and maxi-
mum voltage values measured by the relay. The available
measured values are listed in Table 3.27. No voltages are
metered unless the voltage input option is installed.
This log contains minimlJTI and maximlJTI values gathered
by the relay while not in pickup. The collected information is
compared against previously stored values and the log is
updated. All logged values are time stamped and resetting
the log (see section 3.13.2, address block 8200) will reset all
log values.
